Description
Technical field
The present invention relates to a kind of oval-shaped cast iron piston ring processing technology, belong to the piston ring processing technique field.
Background technique
Piston ring is component crucial in the equipment such as internal-combustion engine, air compressor, directly determines the important quality characteristics such as power, discharging of internal-combustion engine, air compressor.The material of piston ring product mainly contains complex alloyed cast iron, spheroidal graphite cast iron, steel is arranged at present, wherein to adopt alloy cast iron, ductile cast iron material to occupy the majority.On cast-iron piston ring formed product structure, reach just round based on ellipse, the oval-shaped cast iron piston ring work flow is very complicated at present, and the existing relevant flow process of multitool oval-shaped cast iron piston ring pitch cutting technology has: with raw material blank alloy cast iron inblock cast, the casting of spheroidal graphite cast iron binary; The corase grind end face; Spheroidal graphite iron ring hilted broadsword pitch cutting (alloy cast iron does not have this operation); The correct grinding end face; Gold machining is a finished product after finishing.Blank alloy cast iron inblock cast can only be made a slice piston ring (spheroidal graphite cast iron binary), because the technology of piston ring casting process adopts multiple mould more at present, the every superimposed golden cast iron ring of a shared running channel has only individual layer (spheroidal graphite iron ring bilayer).Therefore molten iron utilization ratio and molding sand utilization ratio, cost of labor and energy consumption are all bigger, cast pollutant emission also higher (dust, noise) simultaneously.So be necessary to improve the whenever folded piston ring number of plies, more than double-deck the reaching of promptly whenever folded piston ring.Many bodies of blank casting process can improve 30% above throughput, and energy consumption, pollutant emission also significantly reduce.But also bring many bodies of blank pitch cutting technological problems.
Summary of the invention
The purpose of this invention is to provide a kind of oval-shaped cast iron piston ring processing technology, solve the processing after the many bodies of oval-shaped cast iron piston ring blank are cast, help improving throughput, reduce energy consumption, pollutant emission and cost of production.
The objective of the invention is to be achieved through the following technical solutions, a kind of oval-shaped cast iron piston ring processing technology, comprise as many bodies cast-iron piston ring blank to be processed, last processing technology correct grinding end face and gold machining, it is characterized in that before described technology also is included in the correct grinding end face many bodies cast-iron piston ring blank to be processed being carried out pitch cutting technology, pitch cutting technology is that many bodies cast-iron piston ring blank is clamped in the anchor clamps with floating clip, and anchor clamps are clamped in the three jaw chuck of working machine tool and carry out.
Described have the anchor clamps of floating clip by the fixture of plate-like, plate-like fixture one side radially equi-spaced apart through three floating clips of bolt movable fixed, each floating clip has fixed hole near its two ends, has fixing threaded hole on the corresponding plate-like fixture, plate-like fixture inner side surface is provided with positioning ring, and many bodies cast-iron piston ring blank places three floating clip inner ends.
Cutter outwards cut from many bodies cast-iron piston ring blank inner chamber when described many bodies cast-iron piston ring blank carried out pitch cutting.
Described have the anchor clamps of floating clip by the fixture of plate-like, plate-like fixture one side radially equi-spaced apart through three floating clips of bolt movable fixed, has the plurality of fixed hole on each floating clip, have fixing threaded hole on the corresponding plate-like fixture, many bodies cast-iron piston ring blank places three floating clip outer ends.
Cutter cut inwards from many bodies cast-iron piston ring blank outer side surface when described many bodies cast-iron piston ring blank carried out pitch cutting.
The present invention is for the pitch cutting technology that satisfies oval many bodies cast-iron piston ring blank processing design and for satisfying the special fixture of this technological design, owing to be to adopt the pitch cutting technology that adapts to the processing of many bodies cast-iron piston ring blank, cancelled the corase grind end face in the existing cast-iron piston ring blank processing, because the equipment of piston ring corase grind end face operation has high input, machine, thing, the material consumption is big, having deleted this operation can directly reduce production costs and energy saving, the contaminated wastewater that grinding simultaneously produces has also been stopped, special fixture adopts floating clip, satisfy the processing of oval many bodies cast-iron piston ring blank, outer ellipsoid of floating clip product clamping or interior ellipsoid, cutter is from product cavity or outer side surface processed product, the floating clip clamp face can be adjusted area of contact according to the different ovalitys of cast-iron piston ring blank, with clamping force apply uniformly with product on.Efficiently solve distortion, the abscission ring of oval-shaped cast iron piston ring.The present invention can improve throughput, reduces energy consumption, pollutant emission and cost of production, has remarkable economic efficiency.
